Container



June 14, 1932. J. VAN BUREN CONTAINER Filed April 18, 1930 x INVENTOR J/l/i I qn Bare/7 TORNEYS;

Patented June 14, 1932 PATENT OFFICE UNITED STATES This invention relates to containers.

It is very difficult to pack granular or flaky material, such as soap powder, soap flakes, cereals, etc., in cardboard containers in such a manner that the material will not leak out of the container. This can be overcome by packing the material first in a bag and then packing the bag in the container. This, however, increases materially the expense of packaging. The leakage from cardboard containers usually takes place at the ends or at the portions where the container is closed.

This invention has for its salient object to provide a container or carton so constructed and arranged that the material therein will not leak out at the seated or glued ends or other portions thereof.

Another object is to rovide a container or carton which is easily filled and sealed after filling and which will be stifi' and strong when completed.

Another object of the invention is to provide a blank so constructed that it can be folded to provide a tight container secure against leaka e.

Another ob ect is to provide a blank so constructed that there will be practically no waste material.

Futher objects of the invention will appear from the following specification taken in connection with the drawing, which forms a part of this application, and in which Fig. 1 is a perspective view showin a container constructed in accordance with the invention;

Fig. 6 is a perspective view of a modified form of the invention; and

Fig. 7 is a plan view, on a smaller scale, of the blank from which the container shown in Fig. 6 is made.

The invention briefly described consists of a container formed from a blank having flaps and tabs adapted to fold across the ends of the container in overlapping relation and to be secured to each other, one of the flaps having a short ear adapted to be folded against and to be secured to an end portion of one on the sides of the container, and the other fla having a similar short ear at one of its en s adapted to be folded against and to be secured to the same side of the container and a long ear at its other end adapted to be folded against and to be secured to the end portion of the opposite side of the container. The flaps, tabs and ears are so cut in the blank that there is substantially no waste material. Furthermore, the ears are so arranged that the tabs which are disposed at the ends of the sides of the container are of rectangular form and of the full width of the ends of the sides and cooperate with the ears in sealing the ends of the container against leakage.

Further details of the invention will appear from the following description.

In the embodiment of the invention illustrated, there is shown in Fig. 5 a blank having a body portion comprising rectangular sections A, B, C and D. The blank is provided with fold lines 10, 11 and 12 which are disposed respectively between the sections A and B, B and C, and G and D. A tongue E extends beyond the section D and a fold line 13 is formed between the section D and tongue E. When the blank is folded, the portions B and D form the back and front, or vice versa, and the sections A and C form the sides of the container.

Tabs F and G extend from the ends of the side forming section A. Flaps H and I from the ends of the front or back'section B have lateral extensions H and I which form two of the short ears before mentioned. The flaps J and K from the ends of the other front or back section D have similar lateral extensions J and K from one of their sides and full width. extensions J z and K from their other side which form the long ears. The parts of the blank intermediate the ends of the side section C and the extensions H, J at one end and I, K at the other end, form the tabs L and M respectively.

From the showing of the blank in Fig. 5 it may be seen that the cartons made as described are made with no waste of material.

The blank is folded on the lines 10, 11, 12, and 13 into the rectangular shape shown in Fig. 2 and the tongue E secured to the inner adjacent surfaceofthe section-A. The tabs F and L are then folded inwardly on the lines 14 and 15. As these are rectangular and of the full width of the box they serve to hold the sections B and D in parallelism and the sections A and C at right angles thereto. Next the flap H is folded down on the line 16 onto the tabs F and L and secured thereto, if desired. Then the flap J is folded down on line 17 onto flap H. Finally the short ears H, J and the long ear J 2 are folded against and secured to the sides C and A respectively.

The other end of the carton, as shown in the drawings, is similarly made. The new construction is especially desirable for the filling end, as the other end may be folded and glued on a mandrel so that the ordinary form flap construction may be used for it, if desired.

By the new construction, the corners of the carton are reinforced and every meeting edge is overlapped and covered. Thus, with a minimum of material a leak proof carton is produced which is unusually rigid and strong.

If it is desired to have all of the ears alike,

the blank may be cut, as shown in Fig. 7. A small ear I-I extends from the right hand end of flap H, being cut out of the material which forms the tab F, leaving the latter as shown at F. At the left hand end of flap J is another small ear J The other end of the blank may be cut similarly. When this blank is folded it will form the carton shown in Fig. 6.
